To all whom t may concern.'

Be it known that we, JAMES M. PHILLIPS and HENRY D. PHILLIPS, citizensof the United States, and residents of Stanford, in the county ofvLincoln and State of Kentucky, havey invented certain new and usefulImprovements in Concrete-Block-Making Machines, of which the followingis a specification. y

This invention relates to concrete block. making machines and has forlits yobject the provision of a device which will thoroughly tainp theconcrete block forming mixture into moving` moulds so that the finishedproduct will be in such a state that the same V may be removed from themouldsat a predetermined point in the travel of the mould carrier and behandled without injury to the green blocks. Y

Another object of the invention is the provision of a tainpiiig devicewhich will tamp the green materials .into moving moulds without injuryto said moulds, the tamping face of the device being corrugatediii a`manner to direct the `lines of force at an angle .and rearwardly of thevertical rather than in a direct vertical manner.

iiother object of the invention is the provision Vot a mould blockhaving ai pivotally Vmounted base whereby the iinished product nfiayA bereadily removed from the mould by tilting the base. l'

Astill fur her object of the invention is the provision of an adjustmentfor elevating the bases of the moulds for forming blocks of Vvaryingheights.

y Another object ot the "invention, is the provision of a shearing`plate for the tops of the green blocks and which is pivotally connectedto the tamping head and oscillated thereby. Y

i A still further object ,of the invention is o the provision ofgadriving mechanism for the moulds which 'is simple, eiiicient and whichwill periodically feed the moulds beneath the taniping head.

This invention will be best understood from aconsideration of theAfollowing detailed description, in view of the accompanying drawingforming a part of the specification; nevertheless itis to be understoodthat the invention is not confined to the disclosure, being susceptibleof such vchanges and modifications which shall define no inaterialdeparture from the salient'` features of the invention as expressedinthel appended claims.

Referring more particularly to the drawings itkwill be seen that theframe'or'bed upon which the track and the moulds are supported isentirely of angle iron const-ruction and a sufficient ,number of irons(are employed for the purpose of providing a vibration incident machine.

to the operation of the -which are in turn connected by means ofreinforcing bars 6. 4A plurality of trans- The frame consists of aplurality of kverti- `cal standards 1 and 1a whichare connectedllongitudinally by means of rside barsv 2 .and base bars3. At the extremeopposite ends of the frame are located pairsf of vertical standards 4which are connected by pairs of angle irons y5 transversely of the frameand Vverse bars 7a connect a pair ofthe longif tudinal bars 2 togetherwhich' carry the track above the tamping mechanism for reinforcing thestandards at this point. Bars 7 carrythe track` not only Vunder thetamping head'but those portionsof the track which Y are opposite thetamping head.

` The transverse bars 7 and 7 a are provided with spaced vertical slots8, as shown 'more particularly in Figure; 14 i in which are .adaptedtobe seated-a pair of spaced tracks 9 andy 10. The upper edges iofthetracks 9 and 10 extend sufficiently above the flanges 11 between ytheslots 8 ofthe angle bars 7 and 7a to `support thev bases 12 ofthe mouldsto permit a roller 13 whichdepends 1 from the bases 12 of the moulds tofreely pass the upper edge of the flanges 11, while l the tracks 9 and10. are` supported by thel notches 8 in the vertical flanges of theangle irons. The outerrtrack members 10 are carried to the` oppositeends o'f the machine and curved, as shown at 14, beyond the opvpositeend of vthe block making machine and supported by brackets 1-5 at thesepoints which are secured to thehorizontal angle irons 5. The inner trackmembers 9 ter-l fminate short of theV ends sov that the bases ofthexmoulds are carried entirely by the curved portions 14 of the ,outertracks 10.

The portion of the tracks below the tamper 16 rests upon adjustablebolts 17 which are screwed-into the horizontal angle Virons 7a andlocked in place by means of nuts 18.

The bolts-provide a means vfor elevating the portions of the tracks justbelow the tamper 16 when the tracks are suiiiciently worn from continueduse of the device.V

'The mould boxes are connected fin 4an endless chain and driven aroundthe tracks by a suitable mechanism which willv be presently describedvwith the base pla-tesy 12 resting on the upperr edgesof the tracks 9 and10 and engaged by the rollers 19 projecting laterally from the outerfaces of said tracks.

The roller 13 depending yvertically ,froml the base plate l12 engagesthe inner faces `of the tracks 9 and 10 and cooperates with rma/refr 22is received within the perforations of the linger 2O and the lug 21 andis'pro-` vided with a head 23 'engaged by Va sleeve 24 which, at itslower end, rests upon the upper face of the Vfinger 20. A sleeve 25 onthe pin 22 below the lug y21 engages said lug and ismaintained inposition ony the pin22 by means ofy a perforated "disc 26.

28 (Figure 11) and adapted to be received between the finger 2O and thelug 21 andv receives the' pin 22 whereby the opposite ends of the baseplates 12 are pivotally connected together and Vform an endless chain. f

A pair of cleats 29 are rigidly secured to and a cotter pin '27. y TheVopposite end of each base plate perforated as shown atv the upper facesof each base plate and provided with a perforated projecting end 30adapted to receive a bolt 31. Saidfbolt is adapted to pivotally connectthe VU-shaped member 32 to the outer free` end 30 ofV each cleat.

, An arm 33 has return bent portion 34 Y.

adapted to engage thev under face ofthe base plates 12 when the mould islocated iny 'f a tilted position. A bolt 35 passing through perforationsin the bridging portion of the U-shaped member 32 and the perforation 36of the arm 33fis adapted toklock said arm to the U-shaped member. Apartition plate 37 'is secured in a vert-icalv position' at the forwardend of each base plate 12. Each of the arms v33 are perforatedv asshownat 38 to receive a bolt 39 which is screwed into a cleat 40 secured tothe pallet`41of the mould per se.

A sleeve 42 on the bolt 39Vis adapted to determine the space between thebottoms 41 Y,

of the moulds and the arms 33. The length of the sleeve 42 alsodetermines the height of the blocks 43 formed in the moulds.

table 44 is located adjacent the point where the blocks 43 are removedfrom the moulds when the moulds are tiltedlaterally'from the bases 12.

4At each end `of the frame is placed a driving spider 45 and an idlingspider 46. The spider 46 is mounted onv the upperend vof a verticalshaft 47 'j upon which the spider idly revolves while spider 45 isrigidly cong nected with the upper end of the driven Vshaft 48f Thelower end of shaft 43 is connected with a worm gear 49 which .in turnmeshes with 'a worm 50 on the end of. a drive shaft 51.` This shaft isextended towards the center of the machine and kis provided with a,bevelled gear 52 meshing with a pinion 53. Pinion 53 is rigidlyconnected with a shaft 54 and a 'clutch mechanism 55 connects shaft 54with the shaft 56 when a leverv 57 is operated to throw the clutch inposition. The lever 57 shown more particularlyv in Figure 2, isvpivotally connected at 58 on a transverse bar 7b and yextendsforwardlyor rearwardly A.and abovev the spider 46 where-it may beconvenientlygrasped by the operator for operatingthe clutch. i y

T heupper endofshaft56is provided with v a gear 58 meshing with a:pinion 59011 a driving Vshaft 60. The shaft 60 is mountedV 'Locatedbetweenthe'spaeed'vertical standards`1a at one portion ofthe track andbelow the tamper 16 are a pair ofspaced-side walls 66 which aremaintainediinposition by means of blocks 67. VBy placing narrower blocksbetween the side walls 66 and the vertical standards 1a wider buildingblocks may be produced inthemoulds when desired. f course, "the palletsof the moulds must be correspondingly enlarged-to i to be received by apassage inthe elevated j the other end of the bar 82 is provided with`meetthe changed condition. These side lwalls 66 extend very =nearlythelength of the machine and adjacent the moulds where the ftamping ofthe 'material within the moulds yis accomplished. A hopper 68 is locatedabove'the moulds and at the rear of the tamper 16 is adapted to feedmaterials 69 into the moulds which is compressedlby the tamper head 16.Y

An eccentric 70 is mounted on the shaft above the side Walls 66 and isadapted end 71 ofthe tamper 16. The tamping of the flatportion 7 2 ofthehead of the tamper 16 has corrugated under face which is so constructedthat the corrugations 73 form a short concave face while the portion 74of the corrugation forms a longconcave face' and the two togethercombinato provide a transverse convex rib 75. Avribv76 isfformedintegrally with the upper wall of the tamper head and extends from'thecylindrical portion 71 of the tamping head to the lower reduced endwhich has a straight Yportion 47. YThe lowerv end of the rib is providedwith atransverse passage' through which is inserted a bolt 78to whichareY connected the links y7 9. These links are supported-attheirupper'ends by means of a rod 8O secured inl bearings 81 on, the angleliron bars A82. 'The angle iron bar 82 is pivotally connected at 83 onone ofthe vertical-standards 1ay `while an arcuate'shaped lslot 84adapted to .receive a bolt 85 'mounted on the other angle iron bar la.
